What Q4232 covers
Corplex is a branded tissue product used to cover a wound during a skin-substitute graft application. Q4232 identifies the material by square centimeter, rather than the clinician’s work of preparing the wound and applying the graft. The treating clinician, such as a physician or other qualified practitioner in an outpatient wound clinic, documents the wound site, Corplex product, and amount used. A lower-leg ulcer treated with Corplex is one example.
Report the Corplex quantity in square-centimeter units and pair Q4232 with the appropriate primary application procedure, such as 15271 when the site and treated area meet that code’s criteria. The record should support the product selected, area treated, and units billed. Under CMS’s add-on designation, Q4232 is billed only with a primary procedure and is paid within that procedure’s global period. CMS classifies Q4232 as technical-component-only; a separate code covers interpretation rather than this Corplex line.

How to choose
- 15271Skin substitute graft
- 15271 describes the graft-application procedure for qualifying sites and treated areas. Q4232 identifies the Corplex material used with a primary procedure.
- Q4234Wound product
- Both are measured per square centimeter, but Q4234 identifies Xcellerate. Report Q4232 only when the documented product is Corplex.
- Q4236Carepatch
- Q4236 identifies Carepatch by square centimeter. The product documented for the application distinguishes it from Corplex under Q4232.
Q4232 billing questions
Does Q4232 replace the graft-application procedure code?
No. Q4232 identifies the Corplex material and is reported with the applicable primary application procedure, such as 15271 when its site and area criteria are met.
How are Q4232 units determined?
The unit is one square centimeter of Corplex. Document the product and amount used to support the units reported.
When would Q4234 be reported instead?
Q4234 identifies Xcellerate, not Corplex. Choose the product code that matches the material documented for the application.
Does Q4232 carry its own global period?
CMS treats Q4232 as an add-on paid within the primary procedure’s global period. It must be billed with a primary procedure.
Does Q4232 include professional interpretation?
CMS classifies Q4232 as technical-component-only. Interpretation is covered by a separate code, not by the Corplex material line.
